An Exponent is a mathematical notation that implies the number of times a number is to be multiplied by itself.
There are some algebra rules and formulas for exponents and they are useful in evaluating certain expressions.
The exponents can be positive, negative, or zero.
In the expression a7, the exponent is 7. 'a' is the base.
In 24, 4 is the exponent. It indicates that 2 is to be multiplied by itself 4 times.
24 = 2 × 2 × 2 × 2 = 16
A. 83 Square yards
B. 82 Square yards
C. 81 Square yards
D. 28 Square yards
Correct Answer: B
Step 1: Area of a square = s x s, where s is the side length.
Step 2: = 8 × 8 [Substitute s = 8.]
Step 3: = 82 Square yards
Step 4: So, the area of the piece of cloth in exponential form is 82 Square yards
Q1: What is 3 raised to the power of 4 (3^4)?
Q2: Simplify 2^3 * 2^2
Q: What does a negative exponent mean?
A: A negative exponent indicates the reciprocal of the base raised to the positive exponent (e.g., a^-n = 1/a^n).
Q: What is any number raised to the power of 0?
A: Any non-zero number raised to the power of 0 is 1.
